The problem can be tracked back from elisp procedure `guix-pcomplete-search-in-help` in guix-pcomplete.el to `guix-help-string` in guix-misc.el, to this problematic code : ``` (guix-eval-read "(help-string )") ```
The procedure help-string exists, as can be seen below : ``` (guix-eval-read "(begin (use-modules (ice-9 format)) (format #f \"~s\" help-string))") ;; => "#<procedure help-string commands>" ``` but the object that `(help-string)` returns seems incompatible with guile's own repl/shell .... The solution might be to just change the `help-string` procedure to return another kind of object, or to fix guile's repl/shell for that kind of object.
